(a, b) be the point of intersection of the terminal

side of with the unit circle. State the unit circle

definitions of the six trigonometric functions.

cos = sec =

sin = csc =

tan = cot =

**Reiny**, Monday, August 13, 2012 at 9:02pmIf Ø is your angle, and since

r=√(a^2 + b^2)

sinØ = b/r

cscØ = r/b

cosØ = a/r

secØ = r/a

tanØ = b/a

cotØ = a/b

These definitions should be in your textbook and are probably defined in terms of x, y and r.

You should memorize them
